An inheritance estimated between $500 million and $1 billion – including a 400,000-acre, oil-rich ranch near Kingsville – was on the line Thursday when the Texas Supreme Court heard arguments in a paternity case involving the famed Kenedy family of South Texas. The question before the court was whether to exhume the body of rancher John G. Kenedy Jr. for DNA tests to determine if the supposedly sterile millionaire fathered a daughter with a maid. Judge Guy Herman had ordered Mr. Kenedy's remains exhumed after preliminary genetic testing appeared to support a claim that Kenedy had an out-of-wedlock child with the maid, whose grandson is seeking the inheritance.Lawyers for the trust, that benefits primarily Catholic charities, argued that the estate proceedings in probate court are final and have been final for over 50 years. They also argued that that in 1948 there was a final judgment in a district court case of John Kenedy's will, and it was made final. The court is not expected to rule for several months on the issue.By:Denton Record-Chronicle, Dentonre.com.For the complete story, click here (last visited October 1, 2005, REO).
